IntroductionTraditionally, cannabis is associated with antiemetic action after acute consumption. However, in 2004 the cannabinoid hyperemesis as paradoxical effect of chronic users, after years of exposure described.ObjectivesDescription of the cannabinoid hyperemesis.MethodOLOGYA case is presented.ResultsClinical case of a woman who repeatedly comes to the emergency service because of abdominal, nausea and vomiting pain.This is cyclical and hardly controllable. The gastroenterology service studied in depth with negative results. She was followed up by mental health borderline personality disorder and she consumed cannabis at an early age, 20–30 joints daily.When she reaches abstinence in short periods, ceases digestive discomfort. However, aprece digestive symptoms with each relapse. The present case showed improvement with cessation of cannabis so it probably was the cannabinoid hyperemesis syndrome.ConclusionsThe cannabinoid hyperemesis is characterized by recurrent episodes of nausea, vomiting, abdominal pain, and chronic cannabis use. Temporary relief is achieved with hot baths. Ceases when abstinence is achieved. It is a clinical entity that does not have much information and requires further study.Disclosure of interestThe authors have not supplied their declaration of competing interest.

A clinical case is presented. The reason for admission was for behavioral disturbances and agitation piscomotriz episode in the street: she had gone to a library to “denounce” the police for entering the subway without paying several times. The patient was very distraught because she was heavily guarded (someone had tapped her phone, entered her house, changed objects place, she was chased down the street…). In the psychopathological examination revealed the sphere of language, her speech was fluid, with pressured speech, full of details, with loss of thread and highlighted the presence of neologisms and grammatical errors (changes of subject and predicate…) and changes some letters by others in the same word. She often used sayings incorrectly and, when you are exploring about this fact, objectively presenting alteration in abstract thinking. In addition, it presents self-references on television. The diagnostic impression was chronic psychotic process of years of evolution. In this case, it was decided to administer intramuscular antipsychotic treatment because she was not aware of the disease but presenting good tolerability profile because, otherwise, leave the track and also a good social functioning was sought. Currently, she continues in mental health, she has not reported new crisis and a progressive scan objective improvement in the organization of thought and speech, leaving the psychotic symptoms.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionOften find it difficult diagnostic approach to patients with symptoms that could correspond to several clinical entities. This requires making a correct differential diagnosis to enable a better understanding and addressing the disease in an individualized way.ObjectiveDescribe pathogenetic factors of paranoid schizophrenia highlighting their relationship with drug consumption.MethodsReview of the clinical history of a patient admitted to acute ward of the Hospital General Universitario of Valencia.ResultsA case of a 30-year-old man, whose income is motivated by persistent and structured autolytic ideation occurs. It presents positive symptoms for several years and amotivational syndrome ago. It has a history of cannabis, cocaine and alcohol since he was thirteen and remains abstinent for more than six months ago. Differential diagnosis arises between amotivational toxic syndrome, reactive depressive symptoms to the disease and negative symptoms for chronic psychotic process. Finally diagnosed with paranoid schizophrenia and is included in the program of first psychotic episodes.Today the productive symptoms disappeared and remain negative though with less intensity achieving an improvement in overall activity.ConclusionsConsumption of toxic influences the development of a chronic psychotic process that may appear years later, becoming a etiological and maintainer factor, not only if its consumption continue, but other effects that occur long term amotivational syndrome and worsening prognosis.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionSeveral risk factors make older adults more prone to psychosis. The persistent growth in the elderly population makes important the necessity of accurate diagnosis of psychosis, since this population has special features especially regarding to the pharmacotherapy and side effects.ObjectivesTo review the medical literature related to late-life psychosis.MethodsMedline search and ulterior review of the related literature.ResultsReinhard et al. [1] highlight the fact that up to 60% of patients with late onset psychosis have a secondary psychosis, including: metabolic (electrolite abnormalities, vitamines defficiency…); infections (meningitides, encephalitides…); neurological (dementia, epilepsy…); endocrine (hypoglycemia…); and intoxication. Colijn et al. [2] describe the epidemiological and clinical features of the following disorders: schizophrenia (0.3% lifetime prevalence > 65 years); delusional disorder (0.18% lifetime prevalence); psychotic depression (0.35% lifetime prevalence); schizoaffective disorder (0.32% lifetime prevalence); Alzheimer disease (41.1% prevalence of psychotic symptoms); Parkinson's disease (43% prevalence of psychotic symptoms); Parkinson's disease dementia (89% prevalence of visual hallucinations); Lewy body dementia (up to 78% prevalence of hallucinations) and vascular dementia (variable estimates of psychotic symptoms). Recommendations for treatment include risperidone, olanzapine, quetiapine, aripiprazole, clozapine, donepezil and rivastigmine.ConclusionsDifferential diagnosis is tremendously important in elderly people, as late-life psychosis can be a manifestation of organic disturbances. Mental disorders such as schizophrenia or psychotic depression may have different manifestations in comparison with early onset psychosis.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionThe use of long-acting injectable antipsychotics is useful in patients with low therapeutic compliance.ObjectiveTo present the demographic and clinical data of a case series in which long-acting injectable aripiprazole has been prescribed in an ambulatory Mental Health Center.MethodsSystematic review of the related literature and clinical history of patients in which long-acting injectable aripiprazole had been prescribed from January to March 2015 in a Mental Health Center.ResultsWe found 10 patients, whose diagnosis were schizophrenia (4), non-specified psychosis (2), personality disorder (1), bipolar disorder (1), schizoaffective disorder (2), of whom 7 were men and 3 women, with a mean age of 43.8 years old. The mean of years since diagnosis was 15.1 years. In 7 patients, we found concomitant treatment with another antipsychotic agent (low dose quetiapine in all of them); antidepressants in 1 patient, benzodiazepines in 6; mood stabiliser in 5 and biperidene in 1. In relation to previous antipsychotic drugs, we found: aripiprazole 15 mg/day oral (4); long-acting injectable paliperdidone 150 mg/28 days (2) paliperdone 6 mg/day oral (1); combination of paliperidone 6 mg/day oral plus olanzapine 5 mg/day oral (1). Only 4 patients had used long-acting injectable drugs previously in their lifetime. The reason of having initiated treatment with long-acting injectable aripiprazole was sexual disturbance (3); lack of compliance (4); clinical inestability (2) and motor side effects (1).ConclusionsIn our series, we can observe a chronic patient profile, predominantly men with diagnosis of psychotic spectrum.Disclosure of interestThe authors have not supplied their declaration of competing interest.
